What's the trouble?

The barrel of the cannon rubbed into the rock.

Due to the angle, the distance behind the tank is also very short, and it is impossible to reverse at all.

The only way is to forcibly turn the turret and forcibly "cut" the barrel out of the stone. This means that the turret needs to be turned at least fifty degrees or more.

However, the barrel is inserted into the rock, and forcibly turning the turret may cause the working motor to burn out.

After all, the turret itself weighs more than ten tons!

Coupled with the resistance of the stone rock to the barrel, the bearing capacity of the motor is very deadly.

Both Ding Mao and Peng Deming are very worried about the motor overload.

After all, this is a tank!

It's not an excavator again.

There are also hydraulics.

Who knows if the hydraulic system of the turret will be able to support it?

You must know that the hydraulic system used by the Type 59 tank is relatively old. The capacity is only about 100 Pa. Exceeding this pressure will "burst".

What are the consequences of the burst?

It's just that the turret can't turn anymore. Stuck on.

What are the consequences of jamming?

The entire Sichuan-Tibet line is going to be blocked here.

Unless the blasting method is used, it is impossible to pull the barrel out.

But......

Blasting in such a dangerous place......

Not even the most experienced Demoman would dare!

Don't make a loud bang and the whole mountain will fall. Directly buried all the tanks alive.

It's a pity!

The hydraulic standards of the obsolete Type 59 tank were too low.

And in today's world, the most advanced tanks, such as the Leopard 2 and the like, have a hydraulic system that can withstand more than 250 Pa.

The gap between the two sides can be seen. Not at all at a level.

Indeed it is.

The Type 59 tank can only be considered the first generation.

Now they have developed to the third and fourth generations. The first generation of antiques has long been thrown into the Mariana Trench.

"Let's go around. No problem. Wang Buan said confidently.

"Are you sure?" Peng Deming was skeptical.

"I'm sure. Wang Buan said affirmatively.

Of course he was sure.

Because the hydraulic system has been replaced.

When he built the universal chassis, he also strengthened the hydraulic system attached to the chassis.

The new hydraulic system has a capacity of more than 5000 bars. What is a small 250 Pa? Not to mention a 10-ton turret. Even if it's a hundred tons, it's easy.

"Good!"

"Turn!"

Ding Mao categorically ordered.

Wang Tianlai personally turned the turret.

Sure enough, the barrel slowly forced a crack in the rock.

"Whoa!"

"Boom!"

Rocks fall off in large chunks.

People who don't know the details think that a landslide has happened.

The place where the barrel crossed was almost all granite, which was very hard. But it was always impossible to stop the strong pressure of the barrel.

Eventually, the barrel was successfully detached from the rock.

Everyone hurriedly checked the rotating motor.

It's okay.

Check the hydraulics.

Normal.

The only thing that is not normal is the barrel.

Due to the strong resistance of the rock, the barrel showed a certain degree of bending. Apparently it doesn't work properly.

Fortunately, it is an old 100-mm rifled gun, which is not expensive to build, and it is not heart-wrenching to damage.

If it was a brand new 120-mm smoothbore gun, the losses would have been great.

Wang Hao, Wang Tianlai, and Wang Yongbo were all criticized.

Continue on the road.

The atmosphere inside the carriage was a bit dreary.

After all, all three of them have been criticized. Naturally, the mood will not be very good. No one was in the mood to talk.

Wang Buan didn't speak either.

He was silently pondering the rifled gun.

Obviously, this rifled gun with a caliber of 100 mm is not of great quality in itself. It's not strong enough.

If the strength is enough, it can be used as an excavator.

Wang Bu'an tested it with the No. 1 robot elf and found that the alloy used in the barrel had a yield strength of only about 300 Pa.

Obviously, such a yield strength is far from enough. The yield strength of the aircraft carrier deck steel is more than 800 Pa. As the barrel of a tank gun, even the deck steel of an aircraft carrier is far inferior, and it is obviously very backward. The only benefit, I guess, is that the cost is cheaper. It doesn't hurt if it's broken.

However, the focus of Wang Buan's attention is not the barrel.

This is the scope of research of the defense industry.

There are special research institutes that are responsible for delving into tank guns. There is no need for him to meddle.

His focus is on motors and hydraulics.

These are two great business opportunities.

In other words, it is also the two weaknesses of China's manufacturing industry.

High-power motors have very high requirements for raw materials and manufacturing processes. The requirements for reliability and stability are also very high.

The hydraulic system has always been relatively backward. China's own scientific research strength is not strong.

Hydraulic transmission has become an important basic technology for modern mechanical equipment and mechanical and electrical products, and has a wide range of applications in the field of industrial machinery.

The application fields of hydraulic systems include: industrial production (forging machinery, injection molding machines, machine tools, machining centers, robots, mining machinery, packaging machinery, etc.), mobile machinery (construction machinery, construction machinery, agricultural machinery, automobiles, etc.), aerospace (aircraft, spacecraft, satellite launchers, etc.), ships (ships and ship deck machinery, operation and control systems), marine engineering (offshore development platforms, submarine drilling, underwater operations, etc.).

Taking foreign countries as an example, about 95% of construction machinery, 90% of CNC machining centers, and 95% of automated production lines use hydraulic transmission.

It seems that the excavator used by Zheng Haifeng is a lot of money, no matter what brand it is, the core technology is actually the hydraulic system.

Those of the world's largest super excavators, super cranes, etc., the key technology is also the hydraulic system.

As for the military industry, the hydraulic system is even more important.

The landing gear, wings, and various transformations of the aircraft all need the support of the hydraulic system.

The take-off and landing of aircraft carriers, blocking cables and so on, not to mention.

However, China's hydraulic system technology has always been backward.

Some companies even cheat.

It was reported in the news before that a large enterprise in Lu Province had a situation of technical fraud.

The hydraulic pumps they purchased from Toei Kawasaki were repainted and labeled with their own brands, and they passed the national acceptance.

Using similar tactics, the company defrauded the state of up to 1.5 billion yuan in scientific research funds.

The matter was exposed, and the whole country was in an uproar. The company involved went bankrupt.

But the industry is not impressed.

Some people even broke the news that there are many similar companies.

On the one hand, it's our technology that doesn't work. No one wants to sink down and concentrate on research.

On the one hand, it is the urgent need of the country for the hydraulic system. Do not hesitate to use high funds to stimulate enterprise innovation. As a result, some ill-intentioned people took advantage of the loophole.

What does this mean?

It shows that our country really needs a high-precision hydraulic system.

Both military and civilian.

Military ones aside. Let's do a good job of civilian first.

Let's defeat Komatsu, Hitachi, Carter, etc. first. Otherwise, the world's high-end excavator market is always someone else's.

Purely from the perspective of construction machinery, we are indeed a super manufacturing power.

However, the mid-to-high-end hydraulic system still needs to be imported.

Someone else can handle you at any time.

There was a sudden traffic jam ahead.

But someone's car broke down.

This is very common. Especially above the Sichuan-Tibet line.

It's just that the location of this car break is a bit special. It happened to be on a very narrow stretch of road. There's no way to get a car. Causing both ends to be blocked.

The road is only about four meters wide. On the left is a dug cliff. On the right is the tumbling river.

If you are not careful, you may fall into the icy river water, and no one can save you.

The tank that Liang Ge was riding in happened to be the first car, so he went down to check it out.

"Grass, what a broken car! Just push it into the river. ”

"The tank is coming! Get out of the way!"

"Comrade PLA, use a tank to push that broken car away!"

"What a broken car! I can't even walk the Sichuan-Tibet line! Throw it into the garbage heap as soon as possible! Or push it into the river!"

"Is it okay for someone else to be a Land Rover?

"Get out of the way!

When a tank convoy arrived, many people were excited.

But they were all blocked at both ends, and they were very unhappy.

Wang Buan climbed out of the tank and stood on the top of the turret to watch the excitement. The damage was found to be a Range Rover. The hood has been opened, and several young men are tinkering.

Vaguely, it felt like one of them seemed a little familiar. But it's too far away to be recognized.

He didn't care. Anyway, Liang Ge has already gone to the front to deal with it.

There should be results soon.

"That's what the British stuff is. Wang Hao said.

"That's what the Indians produce. Wang Tian said.

"That's even more unreliable. Wang Yongbo finally concluded.

As if to confirm his words, Liang Ge went to the front to deal with it for a while, but the Range Rover still didn't drive away.

On the contrary, the crowd of onlookers is increasing. Someone started to shout impatiently.

After all, Wang Buan is a teenager, and he can't help but run to the front to see the excitement.

It's okay if you don't look at it, but when you look at it, it's an acquaintance again.

Or a former enemy.

Tan Bowen.

The owner of a Range Rover.

This guy actually ran to the Sichuan-Tibet line. It's really fate.

Tan Bowen obviously also saw Wang Buan. He was slightly stunned. Immediately, as if he had found a savior, he beckoned to Wang Bu'an again and again.

"What are you doing?" said Wang Bu'an with an expressionless face.

"Help, take us to Zhicheng. There are garages there. Tan Bowen said helplessly.

"How's your Land Rover doing?"

"The engine is broken. ”

"The engine is broken?"

"yes! When is it not bad, but it is bad at this time. ”

"Huh. ”

Speaking of this, Tan Bowen was also very depressed.

I thought Land Rover's off-road ability was very strong. That's why I bought one. On the Sichuan-Tibet line, there are also a lot of Land Rovers. There's nothing wrong with anyone else's.

It's just his own fault. Or is it a problem with the engine. It's not good to fix it at all.

In fact, even if you get to Zhicheng, it is estimated that there is no way to repair it.

Even when I went to Sa City, there was no 4S store.

It is estimated that it will be shipped back to the mainland.

Or find a local non-4S store to get it.

The premise is ......

Able to arrive in Sa Cheng smoothly.

What to do?

Today it is still the fourth watch. Ask for a little referral vote. Thank you.
